"The weaker tone in consumer income suggests that despite recent improvement in labor market activity, incomes have thus far failed to rebound substantially, leaving consumers dependent on savings to finance the recent pickup in spending activity – a largely unsustainable trend," says Gennadiy Goldberg, a U.S. strategist at TD Securities. "While the 0.5% rise in real November spending activity should help buoy economic growth, if incomes continue to lag, the consumer spending tailwind to economic growth may begin to dissipate. We nevertheless expect consumer incomes to rebound in the coming months as economic growth shifts up a gear and the recently substantial pace of job creation leaves more income in consumers’ pockets."
